Chrysler Jeep Patriot MOT Failures

An analysis of 10,403 real DVSA MOT tests on the Chrysler Jeep Patriot — what fails, how often, and how that compares to every other car on UK roads. Generations covered: MK74 (2007–2014).

Where the Chrysler Jeep Patriot fails its MOT

The single biggest MOT failure point on the Chrysler Jeep Patriot is suspension ball joints worn — this model is 86 times more likely to fail on this item than the average car on UK roads. That makes it a major concern for anyone buying or owning this model. Across 10,403 MOT tests, 4.12% of all Chrysler Jeep Patriot tests recorded this as a failure.

Suspension failures typically mean worn bushes, drop links, or dampers. These affect handling and tyre wear. Budget £150–£400 per corner at an independent garage for full suspension overhaul.

Other notable weak points include abs fault (29x the fleet average), emissions failure (57x the fleet average), anti-roll bar links worn (16x the fleet average), and light unit fault (11x the fleet average). These ratios compare the Chrysler Jeep Patriot's failure rate on each item against the national average for all cars tested — a ratio of 10x means this model fails ten times more often than a typical car.

The failures span 4 categories: Suspension, Brakes, Exhaust & Emissions, Lights & Electrics. If you're inspecting a Chrysler Jeep Patriot before purchase, these are the areas to focus on — and if any have been flagged as advisories on a previous MOT, they're likely to become failures in the near future.

How failures change with mileage

The Chrysler Jeep Patriot's weak points shift as the car covers more miles. Understanding these patterns helps you know what to expect — and what to budget for — at each stage of ownership.

60,000 to 100,000 miles

This is where routine wear items start to show up. Brake components, tyres, and exhaust parts have done serious work by this point. Cars that have been well serviced will show fewer of these failures — this mileage band is where good maintenance really separates the well-kept from the neglected.

For the Chrysler Jeep Patriot specifically, the DVSA data shows the most common failures at this mileage are suspension ball joints worn (86x the average) and emissions failure (57x). abs fault (29x) and anti-roll bar links worn (16x) also appear frequently.

Over 100,000 miles

High-mileage cars accumulate failures across multiple systems. The key question isn't whether things will need doing — they will — but whether the car has been maintained well enough to keep on top of them. Look for a consistent service history and recent MOT passes with minimal advisories.

For the Chrysler Jeep Patriot specifically, the DVSA data shows the most common failures at this mileage are suspension ball joints worn (36x the average) and light unit fault (11x). emissions failure (9.7x) and suspension pin, bush or joint worn (7.8x) also appear frequently.

Known issues beyond the MOT

An MOT only tests roadworthiness at a single point in time — it won't catch developing faults, intermittent problems, or issues that haven't yet reached the failure threshold. These are the issues that Chrysler Jeep Patriot specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.

Suspension component corrosion and deterioration (MK74) Dangerous

The Jeep Patriot shows exceptional rates of suspension component corrosion and structural deterioration. Affects MK74; typical independent garage repair cost is £400–£800.

Brake system corrosion and hose deterioration (MK74) Dangerous

The Patriot suffers from severe brake system corrosion issues, with brake hose ferrules corroding at 161.0 times the fleet average rate and brake discs showing excessive corrosion and fracturing at 161.0 times the fleet average. Affects MK74; typical independent garage repair cost is £200–£400.

Shock absorber failure and leakage (MK74) Major

Shock absorbers fail at 1090.8 times the fleet average rate, typically due to seal failure causing oil leakage or complete loss of damping function. Affects MK74; typical independent garage repair cost is £200–£400.

Engine management warning light malfunction (MK74 Diesel) Major

The 2.0 CRD diesel variant shows engine management warning lights at 68.9 times the fleet average rate. Affects MK74; typical independent garage repair cost is £200–£600.

What to check before buying a Chrysler Jeep Patriot

Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Chrysler Jeep Patriot:

Suspension — check for suspension ball joints worn, anti-roll bar links worn, suspension pin, bush or joint worn, subframe bushes or mounts worn. Brakes — check for abs fault, brake hoses perished or damaged. Exhaust & Emissions — check for emissions failure.

Beyond the MOT items, ask specifically about suspension component corrosion and deterioration and brake system corrosion and hose deterioration. These won't show up on a standard MOT but can be expensive to fix — repairs start from £400. A specialist pre-purchase inspection is worth the investment on this model.

Always check the car's full MOT history for patterns — recurring advisories often become failures within 12 months. And verify the service history to confirm maintenance has been kept up to schedule. Enter any reg into our free car check to see the complete picture.
